Extraction of H+, NH4+, Ag+ and Tl+ into nitrobenzene by using sodium dicarbollylcobaltate in the presence of tetramethyl p-tert-butylcalix[4]arene tetraketone
Original language description
From extraction experiments and ?-activity measurements, the exchange extraction constants corresponding to the general equilibrium M+(aq)+NaL+(nb)ML+(nb)+Na+(aq) taking place in the two-phase water-nitrobenzene system (M+=H+, NH4+, Ag+, Tl+; L = tetramethyl p-tertbutylcalix[4]arene tetraketone; aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Moreover, the stability constants of the ML+complexes in water saturated nitrobenzene were calculated; they were found to increase in the order Tl+<NH4 +<Ag+ <H+ <Na+.
